What does it do when you try to start it? does it at least turn on? Is it no cranking over?

Shelly, welcome to the Forum. May I ask how you determined that you needed the sensors? Did you do the key dance? Also, did you use Chrysler sensors, as our PT's do not like aftermarket sensors.

As Hooligan asked, did you use a genuine Chrysler Part or a sensor from an auto store? Some (or most) after market sensors either don't work at all or not for very long. There's also cases (including mine) that the wiring harness (which runs from the sensor along the back of the engine rubbed against something that chaffed the harness and broke of the wires inside the casing.

Also did you reset your computer after replacing the sensor? As in pull the negative lead for 5 minutes, then reconnect.

yes my husband done all of that and found crack on edge by screw housing in new camshaft sensor. would that stop it from starting? also he says codes p0522 and p0340 show up on dash, why is that?

A small crack on the sensor shouldn't hurt but if it's a new sensor from Chrysler. I'd take it back, unless your husband put too much pressure on the screw while tightening it down and broke it himself.

No this will sound odd and it's not supped to work like this (I think) but a few owners have told the same story about the engine stalling with a P0522 code (oil pressure sensor low) and I stopped one day while on patrol and two elderly ladies with a PT were stalled at the traffic light. Kept turning over the engine and it wouldn't start. Told her how to do the key trick and sure enough it was the P0522. Knew what it mean but didn't make since. That code should stop the car from starting. Got her a tow to the nearest Chrysler dealer, they couldn't find anything wrong but changed the oil sensor anyway (like any good dealer trying to make money) but sure enough, the car started up and ran fine. Maybe there's some sort of fail safe that if the computer sees a low oil pressure fault from the sensor, it wont' let the engine start.

Haven't done it, but supposedly not too bad of a job to replace that sensor.

AND, after reading what yo said, you didn't get a Chrysler sensor. It probably says "Made In China/Singapore/Malaysia/Whatever" on the box.
